3,153,407 ROTARY CGGKING TGP FR A HME j AFFLIANCE Hamid lL. Frick, Hamilton, hio, assigner to Whirlpool Corporation, a corporation of Deiaware Filed Aug. 22, 1961, Ser. No. 133,237 I9 Claims. (El. 126-37) This invention relates to a kitchen appliance having Y a rotatable cooking member containing a cooking unit such as a` cook top that is movable from and to a storage position.

In the appliance of thisinvention there is provided a cooking member such as a cook top containing a cooking unit or units such as burners with the cooking member being in a storage position to conceal the cooking units when not in use, but being movable from this storage position to a projected position. This projected position may be attained by employing means for simultaneously rotating the cooking member and moving member forwardly to a projected position for use or may be merely by rotating the cooking member. In either alternative the cooking unit or units such as the burners are moved into a position for ready access for use in preparing food and the like.

One of the features of this invention is to provide such a cooking member having improved means for moving the member from a retracted position such as a storage position to a projected position for use, with this moving being achieved either by rotating the member or by simultaneously rotating the member and projecting the member forwardly into position for use from a retracted storage position.

Other features and advantages of .the invention will be apparent from the following description of certain embodiments of the invention as shown in the accompanying drawings. Of the drawings:

In the embodiment of FIGURES l-S inclusive there is provided a rotatable cook top 11 with an upstanding back member 17 (FIGURE 2) located in the chamber 4I2 of a cabinet I3 (FIGURE 1). The cook top Ii includes a horizontal shelf 11a providedwith'four cookvtion by a plurality of screws 27 (FIGURE 5).

ing units or burners which may be either gas or electric and which as indicated at 14 (FIGURE 8) are electric. The counter tops 15 have a recessed cabinet area 16 between them. Between the counter tops, cook top 11, supported by cabinet 13, is moved into position for use of the cooking units 14.

As shown in FIGURE 8 the rear of the essentially semi-circular cook top 11 is provided with a vertical back member 17 which when the cook top 11 is in operating position acts as a splash guard. Then, when the cooking unit 11 has been moved to storage position within the chamber 12 the upstanding back member 17 serves to close off the chamber and hide the shelf 11a and cooking units 14 from view. The exposed side of the upstanding back member 17 when the cook top 11 is in storage position (FIGURE 7) may include a decorative panel. The side of the member 17 adjacent the cook top 11 may be of metal to serve as a splash guard.

The cook top 11 is provided with a sheet metal bottom 18 and curved sides 19 (FIGURE 6). At the rear of the cook top when in projected position there is provided a straight side 2t) (FIGURE l) in the form of a chord of a circle dened by the curved side 19. The y back member 17 extends upwardly from this straight side 20.

The cook top 11 and associated structure provide an apparatus in which the cook top may be rotated in an arcuate motion substantially from the storage position of FIGURE 7 to the projecting or working position shown in FIGURE 8. During this rotation the cook top 1f is also projected forwardly. Means are also provided for disconnecting the apparatus that provides the forward projection it desired.

In the embodiment FIGURES 1-8 there is provided a guide apparatus for guiding the cook top in these movements. This guide apparatus comprises a trst guide member 21 in the form of a rectangular metal plate (FIG- URES l and 3-6) located beneath the bottom of the cook top 11 and hidden from View beneath a lower shelf member 22 which forms the bottom of the recess lo. The guide apparatus which includes the rst guide member 21 projects through an opening 23 (FIGURE 5) in the lower shelf member 22.

The rst guide member 21 of rectangular shape is provided with spaced sides 24 that are displaced downwardly from the plane of the remainder of this guide member as illustrated in FIGURE 5. These sides are provided on the top, bottom and edges with an enclosing solid plastic bearing material 28 which may be Delron, Teflon, nylon or some other heat resistant bearing ma- -terial.` These sides 24 of the rectangular first guide member 21 are supported on substantially parallel raised slide supports 25 which extend forwardly and rearwardly of the recess 16 (FIGURE 1). The spaced sides of the member 2Iare held for sliding movement on the tops of the slide supports 25 by brackets 26 held in posi- The brackets 26 do not bind the bearing material 28 but serve'only as guides for the movement along the slide` second guide member 2i)` which is of circular shape (FIGURES 3 5). As can be seen, particularly in FIGURE 5, the width of the second member 29 is substantially the same as the width of the rectangular first` guide member 21. This second guide member 29 also has a peripheral flange Si) that is here formed upwardly 1 from the plane of the remainder of the guide member and this circular ange or edge 3i) is also provided with bears.

.by this disabling mechanism there is provided a cam 54 engaging the bottom of the'projection '50 and mountedv ta a heat resistant bearing material 3l similar to the bearing material 2S. Located between the edge 3d of the second guide member 29 and the bottom 18 of the cook top is a bearing plate 32 that is generally circular and that is attachedto the bottom of the Cooktop as by screws 33. The plate 32 may be of the same material Vas the slide supports ,125. The screws 33 also engage the outer edge and hold in position a guide bracket 34 Vof circular shape and which embraces the bearing material 3l but likewise does not bind it so. that the cook top 11 is rotatable on the bearing 3,1 with'this rotation being guided by the l bracket 3 4. The lirst and second guidey members comprise a main guide member or means for guiding movement of the .cook surface between projecting and retracted positions in association with other elements such as the guide supports and bearing material.

The two guide4 members 2l and 29 which are attached together are provided with a common opening 35 at the center of the second guide member 29 and forwardly of the center of the first guide member 21 as shown in FlGURES 3 and 4. ln order to simultaneously project the cook top 11 forwardly when it is rotated from the position in FlGURE 7 to the position in FIGURE 8, where such is desired, there is provided a crank and link system for moving the cook top from its retracted position to its projecting position upon rotation of the cook top. In the 4illustrated embodiment this crank and link system comprises a crank element 36 having one end 37 (FIGURE 6) attached to the bottom of the plate Slinwardly of the straight edge 20 of cook top 1l, an intermediate vertical portion 38 extending downwardly through the opening v35 land another end 39 extending away from the verticm portion V38E in the direction opposite to the direction of the lone end 37. The crank :i6/gis so positioned with relation to the cook top 11 that when the cook top is in its retracted position as shown in FlGURE l-the crank 36 will extend forwardly or toward the front. It should be noted that it is Within thel scope of my invention to substitute other motion converting units for crank 36 and link 41 to provide the reciprocatory component for shelf lla. For example, an eccentric cam may be substituted for crank 36 and an encompassing strap follower attached to a pitman may be used to replace link 41.

Attached to the outer end of the portion 39 (FlGURE 6) is one end 40 of a reaction link or leverY element 41. The opposite end 42 of the link 4l is hinged or rotatably attached by means of a screw 43 (shown in phantom in FlGURE 6) to the base member 44 which forms the bottom of the unit and on which the slide supports 25 are mounted (FIGURE 5,). This end 42 of the link 41 is supported above this base member as by means of a spacer block 45 (FIGURE 6.). The lirst end 46 of the link 4 1 is also hinged or rotatably attached to the end 39 ot the crank 36 as by means of a screw 46. element 4i is constructed in two interlocking parts 47 and 48 each made up of an elongated metal strip with the rst part 47 containing the hinged end 40 and overlying the other part 48 which contains the opposite hinged endl 4Z.

The two link parts 47 and 43. are normally heldV together in interlocking. relationship for operationpas a single element by means offa manually operable disabling mechanism including a compression spring 49.` pressing a projecting portion S of the link part 4'7'- into an opening l in the other link 43. This spring isheld in position ,by providing the link part 48 with upstanding slides 52 and overhanging flanges 53 that extend toward each` otherr and against the inner surfaces of which the spring 49 In order to releasethe two link parts 47 and 49 on an axially rotatable rod 55 extending to a point outside the cook top 1l and provided with an unwardly extendingvhandle 56. When the rod 55 is rotated in a The linkV i counterclockwise direction as viewed in FIGURE 6 by depressing the handle 56 of the disabling mechanism the cam 54 moves upwardly to move the projection Slt out` of the opening 51 and thus release the two link parts 47 and 48. Normally, however, the parts will be in the position shown in FGURE 6 so that the link 47 operates as a single link.

The end of the link element 4l is bent or offset as illustrated in FIGURE 1. The purpose of the bending will be explained hereinafter in the description of the operation of the appliance.

When the cook top is in stored position, as shown in FIGURES l, 3, 6 and 7, the crank 36 and lever 4l extend away from each other. When it is desired to move the cook top l1 into operating or forwardly projecting position, the cook top 11 is rotated from the storage position to a projecting position as shown in FIGURES 4 and 8. When this occurs the cook top rotates on the circular bearing material 31 of the second guide member 29 and is held against sideways displacement by the bracket 34. This rotation moves the pivot point defined by the screw 46 to the left as viewed in FIGURE l and upwardly as viewed in FIGURE 3 because of the eccentricity of crank 36. In doing this the link 4l of course moves through an arc about its pivot point defined by the screw rlfhen, as rotation is .continued through idly to move the cook top 1l to the operative projecting position of FIGURE 8, the cook top is simultaneously moved forwardly because the end 42 of the link 4l is pivotally restrained by the pivot screw 43 to crank 36. When the cook top has been rotated to its forwardmost operating position, the crank 36 is against the link 4l with both extending in substantially the same direction. In other words, the cam .and link mechanism formed by parts 3e and 41 provide a reaction mechanism for producing a translatory movement of shelf lla during its arcuate movements so as to produce a resultant compound arcuate and translatory motion of shelf 11a.

During the rotation of the cook top the entire unit slides forwardly on the slide supports 25. During this sliding movement lateral displacement of the cook top is prevented by the guide brackets 26. lfv it is desired merely to rotate the cook top on the second guide member 29 without'moving the cook top forwardly the cam 54 is operated as previously described to disengage the extensible link parts 47 and 48 of the link 4l. As pointed out previously this causes raising of the projection Si! from the opening 5l. When this has occurred rotation of the cook top will cause relative movement of the parts 47 and 48 and thus extending or lengthening of the link 4l so that there will be no corresponding forward movement. Then when the cook top is rotated back to storage position the projection Sti will automatically engage the opening 5l. Link parts 4'7 and 48 can in this way be released from their interlocking relationship by this disabling mechanism which prevents reaction forces from being exerted on the stationary pivot pin 43 and thereby eliminates the translatory component from cook top il during its rotation.

The second embodiment of FIGURES 9 and l() illustrates another arrangement orreleasing the extensible link parts Wand 48. in this arrangement the base member 44 is provided with a raised support bracket 57 extending across :its` front. Immediately on the rear of this bracket 57 there is provided a iiange 58 and a second flange 59 which retain in position an axially rotatable rod 6l) inv theform of a wire. This wireextends transversely of the-unit and has one end 61 bent to form a crank 62 and the other end bent to form a crank 63. Attached to the extreme end ofthis crank 63 isa longitudinally movable operating member 64 projecting through the front -of the device and provided with a knob d5. When it is desired to release the two parts 47 Y and 4S of link 41 it is merely necessary to pull forwardly on the knob` 43S. ,This rotates the rod 60 about its axis and raises the crank 62 to move the projection 50 from the opening 51. Thus the operation of this embodiment performs precisely the same function as the release mechanism of the first embodiment.

An electrical conduit 66, leading from an electrical source (not shown), is fed into tube 67 which is attached to the underside of bottom 18. From tube 67, electrical conduit 66 extends through opening 68 in the bottom 13 and connects to the electrical elements 14 (FIGURE 1). Referring to FIGURES 3, 4, and 9 the offset end 40 of the link 41 permits clearance for tube 67 while the cook top 1l is in the operative position. If link 41 was to be placed on the horizontal centerline, as viewed in FIGURE 4, it would contact tube 67 (not shown in this view) which is beneath and concentric with opening 68 and would not allow a full 180 rotation. However, by ollsetting link 41 clearance is maintained and a full 180 rotation is insured.

It will be noted that in both embodiments of my invention the resultant compound rotary and translatory motion of cook top 11 as produced by rotation of cook top 11 is made possible by the circular guide 34 which accommodates the rotary motion imparted to guide plate 29 and by the side supports 25 and spaced guides 26 which accommodate the translatory movement of plate 21 which is caused to move in a linear motion as a result of the reaction forces imposed by this rotational movement on the crank-link system 36, 47, and 48 through the shiftable pivot pin 46 and the stationary pivot pin 43. In both embodiments this resultant motion can be changed to pure rotary motion by a disabling mechanism capable of disconnecting the rigid interlocking of members 47 and 4S of the compound link formed by these two members.
